Description copied from interface: ProcessingTimeCallback

This method is invoked with the timestamp for which the trigger was scheduled.

If the triggering is delayed for whatever reason (trigger timer was blocked, JVM stalled due to a garbage collection), the timestamp supplied to this function will still be the original timestamp for which the trigger was scheduled.

Specified by:

onProcessingTime in interface ProcessingTimeCallback

Parameters:

timestamp - The timestamp for which the trigger event was scheduled.

Throws:

Exception

                      long currentProcessingTime,
